SYSTEM OF PUMPING.

SPECIFICATION forming part of Letters Patent No. 226,008, dated March 30, 1880.

Application. filed July 10, 1879.

To all whom it may concern:

Be it known that I, CHARLES TYSON, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented an Improved System of Pumping, of which the following is a specification.

My invention relates to a new system of pumping where water is desired to be lifted some distance and in which the column of water lifted regulates and governs the pressure of steam to drive the pump. Furthermore, by the arrangementand construction and connection between the water-pipes and steamgenerator, it is impossible to blow up said generator or boiler, thus rendering it safe.

My invention consists in the construction and arrangement and operation of a steampump, generator, and necessary pipes, as hereinafter described, and which constitute a new system of pumping.

The object of my invention is to construct a system of pumping for house use particularly, which shall be perfectly safe, simple, and selfregulating, and which is an application of a system for which I hold Letters Patent, November 6, 1877, and January 29, 1878.

When my system is used for steam fire-engines the stand-pipe is dispensed with, and the pressure is obtained by the use of an airchamber or other suitable pressure device.

In the accompanying drawings, Figure 1 is a perspective view of the apparatus embodying in it myimproved system of pumping. Fig. 2 is an elevation of same with the front part of the generator-shell taken away to show the generator.

A is the steam-generator shell, which incloses the generator proper, B, which is composed of a number of coils of pipe, preferably of copper. O is the grate upon which the fire is built. If the system is worked on a small scale, a gas-jet may be used in place of a coal-fire. The bottom of the coil B terminates in a pipe, D, which is supplied with a steam-valve, K. The pipe D communicates with the steam-chest of the steam-cylinder of the pump E. The piston of the steam-cylinder is of greater area than the piston of the pump-cylinder.

I is the exhaust from the steam-cylinder. F

is the suction-pipe to the pump, and G the discharge and stand pipe, which conveys the water to the top of the house or other high elevation. The upper end of the coil B terminates in a pipe, H, which connects with the stand-pipe G. Through this'pipe H the generator B draws its supply of water.

It would not alter my invention if the pipe H were placed at the bottom and pipe 1) at the top of the generator B; but I prefer them as they are shown and described.

.It is not necessary that the generator be composed of coils, as any other form performing the same function would do; but a coilgenerator of copper is preferable, particularly on a small scale.

Operation: Water being in the generator B and part way up the stand-pipe G, a fire is built upon the grate 0. As steam is generated, there being no outlet but that through the pipe G, the water in the coil-generator B is gradually forced up into said standpipe G. Now, if the valve K is opened and the steam sufficientin pressure to put the pump E in motion in opposition to resistance of the column of water in the stand-pipe G, the said pump will operate and force a stream of water into the stand-pipe G, at every stroke increasing the height of the column, and hence its resistance; but this increased resistance or lift is overcome by the increased temperature and consequent higher pressure of the steam. Now, suppose that the stand-pipe G has been filled and is running over at the top into the tank which is to be filled. It is evident that the pressure of steam in the steam-coil B is equal to or slightly greater than the pressure of the column of water in the stand-pipe G. This being the case, the superior superficial area of the steam-piston over the pump-piston when the steam-pressure and the pressure of the water-column in stand-pipe G are equal, or thereabout, or even if the former were slightly less than the latter, water would be pumped up by the pump E. The generator B draws its supply of water from the stand-pipe G bythe pipe H; but the water in G cannot run in to the generator B when there is sufficient pressure of steam, as before stated. If the steam-pressure should become greater than the pressure of the water in stand-pipe G, it will be forced into said pipe, and then be condensed by contact with a large and fresh body of cold water. Hence it is plain to see that an explosion is impossible, and. further, that the height of the column of water in the pipe G regulates the pressure in generator B. Now, suppose that the fire on grate 0 were taken away. The steam-pressure would diminish, and finally the water from pipe G would pass through pipe H and into the generator 13, filling it, and the pressure of a column of water in the standpipe, from the steam-cylinder up, will then act on the steam-piston, and by the differences in areas of the steam and pump pistons the steam-engine of pump E will be converted into a waterengine, and water will be driven into the stand-pipe G; but at the same time, and for every stroke, a greater amount will be withdrawn by this water-engine, and hence the column of water will be gradually lowered by a differential discharge, until finally the pressure of the column is no longer sufficient to drive the pump E. This is necessary, inasmuch as the water should never get below a certain level in the pipe G, as that water is to give the pressure to the steam in the generator B when next started.

The water-level in pipe G may be prevented from getting too low by closing the valve K.

The exhaust-pipe I of the steam-cylinder could be connected with the suction-pipe F of the pump, as shown in dotted lines in Fig. 2, at I. and then the steam-cylinder would be virtually a low-pressure engine, since all the parts constituting a low-pressure engine would be there.

here it is not possible to use a stand-pipe an air-chamber or other suitable device may be used to obtain the necessary pressure.

I claim- 1. The combination of the generator B, pump E, and stand-pipe G, or other suitable device for giving pressure to the water pumped, all constructed and operating substantially as and for the purpose specified.

2. The pump E and boiler or generator B, in combination with stand-pipe G, or other ordinary water-pressure device, and pipes H, D, and F, all constructed and operating substantially as and for the purpose specified.

In testimony of which invention I hereunto set my hand.

CHARLES TYSON.
